The entrance (32x64) is less than a single world map tile (50x50).
Tiling does not have an advantage, and trolls only attack when a player
is nearby anyways. This makes the map less confusing for map editors and
DMs trying to reset the map.

Also take this opportunity to correct capitalization and make the bridge
troll actually say something (was broken due to typo).

Cosmetic changes to many of the maps - gave them the 'navar look' (westcwall). Renamed maps (which were either unnamed, used the actual file name or tweaked their spelling and capitilization.) Renamed maps with a generic name to something more specific. Other changes are due to Map Editor reformatting.
